Distribution and Abundance: Very local.

Primary Habitat: Grassland.

Flight Period: Single brooded in April and May.

Localities: Collyweston Quarry and Easton on the Hill.

Observations: The Easton on the Hill record was of a single moth taken in a garden light trap on 18 April 1987. As the trap was sited near to Collyweston Quarry it was considered that the moth could have been a wonderer from the reserve. On follow up on 6 May 1988 the species was found to be present and the record was updated on 20 April 1993. All of the moths that I have seen on the site have been ab. brunnea including many reared from a captured female. Apart from in the 1950’s when twelve were taken at an m.v. garden light trap in Wellingborough there are few records over the years. Other localities include Bedford Purlieus 1916 and Castor Hanglands 1933.

L.O.N.: 1907. Ashton, Geddington Chase. At sallow.

First Record: 1902, Victoria County History.
